T0 all w7wm z't may conoern:

Be it known ih-at I, WILLIAM G. SEARS, a eitizen of the United States,residing ab Chattanooga, in the conntyof Hamilton ancl State ofTennessee, have invented certain new and useful Improvements inRail-Ties; and I clo hereby declare the following to bea full, elear,and exaci: description 0f the invention, such as will enable othersskillecl in the art to which itappertains to make anti nse the san1e.

This invention relates to an improvernent in oross-ties for railways,the objeot being to provide a more perfeet metallic cross-tie 01 sleeperWl1ioh may afiord ayielcling elastic 01 enshioned seat for the rail,thns obviating the oonstant pouncling ineident to the use 0i' theordinary railway constrnction, and especially charaoteristie ofinelastic ties of solid iron o1 steel,which results speeclily in tl1einjnry ancl destruotion of the rails and ties; anal the inventionconsists, essentially, in the eombination, constrnetion,ancl arrangementof parts, substantiallyas will be hereinafter clesoribed and claimecl.

In the annexed drawings, illustrating my inve'ntion, Figure l is aperspective view of my improved rail-tie. Fig. 2 is a side elevation ofa railway-rail snpported npon my improved tie to whioh it is seenrecl,the tie being shown in transverse seetion on the linex a: of Fig. Fig. 3is an enlargecl cletail plan view showing one 015 the transverserail-sup porting spring-plates ancl the rail seenred thereon by atrack-fast-ener. Fig.4: is an enlarged partial perspeetive view 0f my impioved metallic tie, showing eertain details of its constrnction.

Similar letters 0f reference designate 001- responding parts thronghoutall. the difierent figures of the drawings My improvecl hollow metallicrail-tie is made in the form of a hollow trongh, gutter, box, 01receptacle, of steel or other metal 0f snitable strength and thicknessancl having a proper length so adapt it forbeing plaeed in the ballastof the road-bed, lilze the ordinary tie, A denoting its bottom, and A Aits sides, which are preferably inelinecl outwardly, the upper edges ofthese sicles A A being provided with horizontal fianges a a, Whieh arenotched 01 indentecl ab a a near each encl, where the transverserail-snpporting plates Applicut-ion file(l April 16, 1890. Serial N0.348,147. (N0 model.)

are to'be seonred npon the tie-box. In Fig. 2 tl1e hollow trough is Seenembedded in the ballast of the roacl-becl, which is firmly pressedaronncl it in such a manner thab tl1e flanges a a a1e on a level Witl1the surfaee of the bed o1 ab a trifling distance above it.

Seenrecl npon the open nie 01 sleeper loox, ne-ar each end thereof, abpoints where Ehe 'rails oross tl1e tie, and ser.ving to support thelatter, a1e flat elastic plates B B, preferably macle of spring-steeland having a convenient ancl snitable thickness ancl Width. These platesa1e preferably arehed, eurvecl, 01 ronncled, so as to be somewhat higherab the midclle than at tl1e ends. They are seeured to the tie in somesniable manner. A preferable way of secnring them is to provide the1n atthe ends with bencls or inturned flanges b, whieh forn1 grooves toreceive tl1e flanges a 011 tl1e nie, ancl also with a oonvenient numberof projections b struek up fromsaicl flanges (see Fig. 2) an l adapted110 enter tl1e notehes a a in the horizontal tie-fiangesa a. Otl1erxnocles of Conneeting the spring-plates may cloubtless be clevised andsnbstitutecl fo1 that here clescribed with good efceet.

O denotes a seouion of a rail that rests npon n1y improved tie, it beingshown for the purpose 0f rn0re clearly explaining ohe invention. Thisrail is seeurecl upon tl1e supporting-plate by some strongtraek-fastening, such as thav describecl in my pencling application forpatent, filed March 15, 1890, Serial N0. 34:3983, and oonsisting,essentially, of' a fixed clamp c, aeting on the inner fiange of the1ail, an onter bar d, having a doubly-inelined face, a bracebloek havingan inclinecl face ancl Wih one sicle pressing against the objeet, and aninierposed wedge f between the outerbar and the brace, said wedge havingis wedgingfaces eacl1 doubly inelined, and the inner elamp, onter bar,ancl braced3loek being fixed in slots in tl1e rail-snpporting plate B,as shown.

' Having thns described my invention, what I clain1 as new, anti desireto secure by Letters Patent, is'

l. The combination of the hollow tie-box having its sicles provicledwitl1 horizontal flanges, the transverse spring rail-snpporting plat-eshaving projections ab alle ends adapted so enter notches in thehorizontal flanges ancl supporting spring-plates having the bends abeaoh end, and oho struck-up projeotions adapted t0 enter the notches intho horizontal fianges, substantially as described.

In testimony whereof I affix my signature in presenee of two witnesses.

WILLIAM G. SEARS.
